The master tasks of forage breeding in China
Since the National Forage Variety Approval Committee and Forage Breeding Committee were established in 1986, we have gone through extraordinary 20 years of forage breeding work.In the initial development period of 10 years ( 1986‐ 1995), the total number of registered varieties was 163,in which the number of new bred varieties was 55, the number of local varieties was 37, the number of the introduction of foreign varieties was 42,and the number of wild cultivars was 29.The main characteristics of this stage was that there were more bred varieties, local varieties and wild species but less foreign variety introductions ; new bred varieties included many kind of species and had strong regional character and adaptability.In the second development period 1996‐2000, 69 new bred varieties were registered, in which the number of new bred varieties was 38, the number of local varieties was 2, the number of introduced foreign varieties was 20, and the number of wild cultivars was 9.The main characteristics of this stage was that on the basis of solid work of old generation plant breeders the new generation of forage breeders improved and bred a series of new forage and fodder crop varieties, and the number of new bred varieties and introduced varieties was large and the number of local varieties and wild species decreased markedly.After 2001, Chinas forage breeding work entered a rapid development period, the main characteristic of this stage was that the number of introduced varieties substantially increased, and the number of bred varieties, local varieties and wild species decreased, however, the total number of registered varieties rapidly increased, breeding technology and tools greatly developed, and the number of breeding organization and breeders increased significantly.
